SCREW-HOLDER.

Specification of Letters Patent.

Patented Apr. 20, 1915.

Application filed April 12, 1913. Serial No. 760,719.

To all whom, it may concern:

Be it known that I, Josnrrr A. DEMERS, a subject of the King of Great Britain, residing at New York city, in the county of New York and State of New York, have invented new and useful Improvements in Screw- Holders, of which the following is a specification.

The general object of the invention is to facilitate the operation of initially 1ntroducing a screw into material forming the back or one of the walls of a relatively deep compartment whose area does not admit of the introduction thereinto at one time, of both of the operators hands. And to this end the invention resides in a holder or tweezer adapted for receiving a turning implement such as a screw driver, and a screw and so holding these parts as to admit of the introduction of the bit of the screw driver into the slot of the screw and the screw so positioned as to admit of the introduction of its end into the material to receive the screw. 7

Other objects will appear and be better understood from that embodiment of my invention of which the following is a specification, reference being had to the accompanying drawings forming a part hereof, in which 1- Figure 1 is a side elevation of the device in use. Fig. 2 is a detail side elevation partly in section. Fig. 3'is a cross section on the line 3-3 of Fig. 1 looking in the direction of the arrows.

lhe screw holder or tweezers forming the subject matter of the present invention is by preference formed of resilient material such as spring steel and is formed so as to have a cross sectional area but slightly greater than that of the ordinary screw driver and this for the purpose of admitting of its being turned in a compartment which would be too small to receive a human hand. In length the holder will be somewhat less than the length of the bit of the screw driver with which it is to be used, whereby to ad mit of the passing of the bit through the holder and into engagement with the screw.

The jaws 55 converge and at their free ends are thickened laterally as indicated at t36, and gouged so as to provide an opening 7 which will conform in contour to the under part of the head and inner part of the shank of the screw 8, when the jaws are in thelr normal positions as shown in Fig. 2. When so positioned the size of the opening 7 will be insuflicient to receive the head portron of the screw 8 so that in order to position such screw, it will be necessary to sprlng apart the free ends of the jaws and when the head portion of the screw is seated to release these jaws, whereby to admit of their clamping the screw between them. But the clamping effect produced on the screw will not be sufiicient to prevent the turning thereof between the jaws.

' The curved portion 9 which connects the lnner ends of the jaws is centrally pierced so as to admit of the passage therethrough of the bit 10 of the screw driver a. The opening had by piercing the part 9 is such as will receive bits of various sizes in point of cross sectional area and compensation is made for relatively thin bits by means of inner spring jaws 1111 suitably fastened to the jaws 55 and having their end portions adapted for conforming to the curvature of the bit and binding on the same when the bit is passed between them so that wabbling of the bit in the opening in'the part 9 and consequent disengagement of the end of the bit from the screw during the operation of turning the same, will be prevented.

A guide 12 is passed between the ends of the jaws 55 and suitably fastened to the jaws. This guide is in the form of a ring whose size is such as will admit of the passing therethrough of the bit 10 and by its presence it will prevent accidental lateral movement of the bit with respect to the screw.

What is claimed as new is:

A screw holder comprising a resilient member having an enlarged arcuate intermediate portion with jaws extending therefrom in the same general direction, a guide located between and fixed to the jaws at points between their ends, and resilient jaws mounted at the inner sides of the first mentioned jaws at points between the guide and the enlarged arcuate intermediate portion of In testimony whereof I affix my signature the said member and having inwardly disin presence of two witnesses.

posed ends located within the said enlarged arcuate intermediate portion ofthe JOSEPH D EMERS 5 said member and disposed radially with re- Witnesses:

other approximately at the center thereof. GEO. A. BYRNE.
